The sugar contents in undiluted molasses were found to be stable on γ-irradiaton. The contents of total sugar and direct reducing sugar in cane molasses were completely unaffected by irradiaiton with doses of less than 3 Mard. The reducton of total sugar content in beet molasses was 2% at 3 Mard. On the other hand, in the molasses diluted with water, sugar contents decreased with the dose. Sucrose in molasses was degraded by irradiaiton, and subsequenlty glucose and fructose were formed. Raffinose in beet molasses was also degraded by irradiatin, but glacose could not be detected. The irradiation temperature ranging from room temperatuer to 61℃, was hardly responsible for the change of sugar contents, but the changes in sugar caused by irradiation were enhanced at pHs of less than 4 and with an excess of oxygen.
